摘　　要：本文根据国家和地区规范、规程的相关规定,对福建省肿瘤医院诊疗中心大楼(26层,高99.9m)冲孔灌注桩持力层选用合理性进行计算。通过计算结果可知,采用不同风化岩层作为桩端持力层,在不同桩长的条件下,其单桩竖向极限承载力相近的结论,并经过沉降验算,沉降量满足规范要求。In this paper, according to the national and regional rules and regulations, the Fujian provincial cancer Hos- pital medical building （ 26 floors, high 99.9m） calculated selection of bored pile bearing stratum of rationality. Through the results using different weathered rock stratum as the pile - tip bearing layers, in the conditions of different pile length, the pile vertical ultimate hearing capacity of the similar conclusions, and through the settlement calculation, settlement meet the requirements of specification.
